In actual applications, Medical hemostatic clamp/clamp of the present invention is held force measuring system and is comprised following three ingredients:
1, fixture and calibrating platform
System adopts chucking power that is ultrathin, the quick pressure transducer direct feeling hemostatic clamp/mosquito forceps different parts (head, middle part and specific part) of power.Based on the principle of unique sensed pressure of this sensor, the burnt black ink namely comprised by structure is stressed and makes induction electrode contact conducting, and its resistance and pressure are inversely proportional to.During each use measuring instrument, utilize the higher leveled standard instruments of precision to carry out quantitatively to sensor, establish the corresponding relation between sensor output and input quantity.Timing signal must provide smooth, clean and hard surface, and require in practical operation convenient, therefore invention additionally provide removable, both can demarcate the platform also can measured.
Contact area size in view of sensor is special and diameter is little, and coordinate the needs demarcated, demarcation device also comprises a set of serial counterweight meeting size needs, power measuring range, and through calibrating weight.The blank area of this sensor adopts the preferred circuit interface of 2.54mm spacing, the Assembly interface that the preferred circuit plug-in unit based on 2.54mm spacing is connected by standard winding displacement, can more emat sensor easily.
2, data acquisition and interface circuit
The quick pressure transducer of ultrathin power is non-loaded, bending time, and impedance is greater than 10M Europe; When there being uniform power to apply on its acting surface, impedance reduces, and the measuring principle of sensor determines that it plays variable-resistance effect in circuit, adopts bleeder circuit to complete power---the conversion of voltage.
Pressure data collection adopts special bleeder circuit as shown in Figure 3, the electric resistance changing of a fixed value is become can reset the resistance of size by the high precision differential pressure gauge of this circuit, and in addition resistance need be connected to analog input, just can reach the object that this changes, therefore can tune to voltage that suitable resistance makes to record in suitable scope, by surveyed magnitude of voltage by connecting line access multi-channel analog signal capture card, amplify conditioning and transform this analogue signal, be directly connected with computer through general serial USB.
3, chucking power gathers Measurement and analysis software
Native system uses the data acquisition of industrial quarters standard and instrument control software LabVIEW to work out the software of the Data acquisition and issuance statistics of Medical hemostatic clamp/pincers chucking power acquisition system.LabVIEW is a kind of graphical programming language, can analyze, shows, judge measurement result, and user interface close friend is easy to operate, is convenient to control objectives instrument.Software configuration adopts the state machine based on queue message processor, there is great motility, allow each branch to control whole message queue completely, user is responded, observing and controlling process is convenient.
Survey Software achieves the input of hemostatic clamp/pincers product information, calibration sensor (preheating timing, multiple averaging), measures chucking power in real time, judges the scope of measurement data, printed product label, print preservation product form, can mutually change in order between each state.Especially in the judge module of data, use real-time pointwise data analysing method, pointwise medium filtering carries out noise elimination, strict stable evaluation algorithm, provide the measurement data meeting required precision, Real-time Collection requirement, the analysis for data provides good basis.
In practical application, medical hemostatic chucking power of the present invention detects the counterweight demarcated and comprise 203.93g, 155.69g, 99.17g, 80.20g, 60.12g, 40.01g and 19.97g as shown in Figure 5 with the weight group in measuring device, supporting in addition have discoid stackable about 20g miniweights, for mixing into other Suitable weight.As shown in Figure 5, the bottom design of each counterweight becomes the disk of diameter 9mm or 11mm, steadily can apply weight, and the flexible collocation of weight.
See in Fig. 1 hemostatic clamp chucking power measuring system, fixture and calibrating platform modular design are the comprehensive platform of coincidence senser overall dimensions and action principle, and structure as dismountable, to change between demarcation and measuring state.The thin film Force Sensing Resistor thin-film force sensor FSR400 type of the InterlinkElectronics company that system adopts, its circular effective active area diameter only 5mm, the counterweight retention system that top is made with a medical silica-gel thick film, center bore diameter 9mm, keeps consistent with the base dimensions of self-control counterweight.
See in Fig. 2 mosquito forceps chucking power measuring system, similar design philosophy embodies wherein.The thin film Force Sensing Resistor thin-film force sensor FSR402 type of the InterlinkElectronics company that system adopts, its circular effective active area diameter only 12.7mm, the counterweight retention system that top is made with a medical silica-gel thick film, center bore diameter 11mm, keeps consistent with the base dimensions of self-control counterweight.
The sensor of above-mentioned 2 measuring systems is fixed with the principle of calibrating platform similar, and 3D figure as shown in Figure 6.Top plate 2, intermediate plate 4 are arranged on base plate 6; Demarcation upper plate 3 is fixedly connected in demarcation lower plate 5, and the two entirety can be inserted in the groove placed in the middle of intermediate plate 4.Demarcate during insertion, measure when pulling down; The shallow slot that top plate 2 front has 1mm dark is for placing slim sensor, and a larger space is opened up for laying sensor interface in rear end, connection standard 9 needle serial port; Poly (methyl methacrylate) plate 1 and liner plate 7 close whole fixture and calibrating platform from top and rear respectively.
The gill portion clamping of Medical hemostat needs special fixture, and as shown in Figure 7, it can be fixed on the adjustable rack-and-pinion travelling carriage of Z axis, and the high-precision realizing difform mosquito forceps easily regulates.Moving jaw 13 is connected on regular jaw 12 by guide pin 14, and moving jaw 12 rear is lined with spring, to finely tune; Location-plate 11 is for connecting this fixture to rack-and-pinion travelling carriage.
